Having received much positive feedback, I considered writing a book on this subject: how to decide about the transition to a pawn ending. However recently an excellent book “Liquidation on the Chess Board” has been written by Joel Benjamin and this persuaded me to reconsider the general concept and change the subject to the exchange of pieces in the endgame. When should we exchange a piece in the endgame and when should we keep it? Why is it so important? How to make a right choice? In this book we ex- amine diff erent types of endings and off er guidance to decide upon the cor- rect decision. We will focus mainly on the exchange of pieces, not pawns. Th e exchange of pawns will be the subject of a separate book. Going through the instructive examples and numerous exercises you will see all the important aspects of the piece exchange in the endgame, and enrich your knowledge and understanding of the fi nal stage of the chess game. Try- ing to solve the positions, you will certainly improve your decision-making ability and analysing skills. Th e fi rst edition of the book was very well accepted by chess players of diff erent levels. I am especially happy that many chess coaches and teachers found it useful for their training programme. Th e book was announced a silver winner of the Boleslavsky Award 2016 by the FIDE Trainer’s Commission. Together with Th inkers Publishing we decided to produce a second, extended edition. I hope it will be successful as well. Eduardas Rozentalis October 2017 INTRODUCTION I would like to start with a complete Th is is a side variation. However, we game.

  • Dvoretsky Lessons 12
    The Instructor Tragicomedies in Pawn Endgames “Pawn endgames are rare birds in practice. Players avoid them, because they do not like them, because they do not understand them. It’s certainly no secret that pawn endings are ‘terra incognita’ - even for many masters, right up to the level of grandmasters and world champions.” N. Grigoriev Herewith, I offer proof that these words, spoken by a famous expert on pawn endings, are true. Without commentary, I give below the final moves of some actual games, and offer the readers the chance to comment on them, to uncover all the mistakes committed by both players.

  • Bobby Fischer's Visits to Colorado – Colorado Chess Informant
    Supplement COLORADO STATE CHESS ASSOCIATION August 2018 COLORADO CHESS INFORMANT Bobby Fischer’s Visits to Colorado Supplement Colorado Chess Informant August 2018 COLORADO CHESS HISTORY - BOBBY FISCHER’S VISITS by National Master Todd Bardwick This supplement to the Informant is an attempt to give a detailed historical account of Bobby Fischer’s visits to Colorado for current and future generations. I have written many articles about it in the Rocky Mountain News over the 17 years I wrote for the newspaper. (To find thoses articles, you can go to www.ColoradoMasterChess.com and click on the Articles link.) This became a much bigger project that I originally anticipated as the list of people to talk to grew. It became a real life “Searching for Bobby Fischer”, just 47 years later. My research on the subject started back in the early to mid 1990s while visiting John Howell. John’s contributions to Colorado chess as an organizer where monumental. I realized that the stories he told were of huge historical significance to the history of Colorado chess. Today, I wish my notes of our conversations were even more detailed and, looking back, there is a lot more I would like to ask him. John passed away on March 7, 2000 at the age of 88. Cathy Howell, John’s daughter, recently helped me to fill in some of the blanks, provided a copy of some of the notes from John’s diaries (he kept a detailed diary for most days of his adult life!), and gave me chess articles and photos from his files dating back into the 1960s which are posted on the History Section of the Colorado State Chess Association website.
